A pacemakers primary purpose is to mantain adequate heart rate by using electrical impulses, delivered by electrodes contracting the heart mucles to regulate the beating of the heart. The pacemaker was invented by Ake Semning (1915-2000) and Rune Elmquist (1906-1996) from Sweden. Ake trained under Clarence Crafoord at Sabbatsberg Hospital, where he and Rune Elmqvist developed the first totally implantable pacemaker. Rune worked as a medical doctor for a while, but then worked as an engineer and inventor. Ake later became head of the Department of Surgery at the University of Zurich and performed the first heart transplant in Switzerland.
